Description

  The present invention relates to a composition comprising ethylhexyl methoxycinnamate, p-menthane-3,8-diol and a hydrophobized metal oxide in a specific average particle size range, and more particularly, The present invention relates to a composition that is excellent in dispersion stability, good spreading, and skin whiteness after application.

  Metal oxides contained in cosmetics and paints are used as raw materials having various functions. In particular, this metal oxide has a feature that various effects can be obtained due to the difference in size (average particle size). When the average particle size is large, it can be used as a white pigment as a colorant. In addition, those having a small average particle diameter have a function of being excellent in ultraviolet ray-cutting effect, and are used for sunscreen cosmetics and the like. However, the smaller the average particle size, the worse the dispersibility in the composition, and it may be easier to form aggregates of metal oxides. In general, sunscreen cosmetics contain a metal oxide having a small average particle diameter and an organic ultraviolet absorber as an inorganic ultraviolet scattering agent in order to have an ultraviolet ray blocking effect. In some cases of containing ethylhexyl methoxycinnamate, a metal oxide having a smaller average particle size may easily form an aggregate.

  As a method for solving these problems, a technique for improving dispersibility by surface treatment with solid and liquid compounds at room temperature (see, for example, Patent Document 1), dispersibility is improved by surface treatment with alkylalkoxysilane. Techniques (see Patent Document 2), techniques for dispersing powder in an oil phase using methacrylic acid-containing acrylic silicone (see Patent Document 3), and the like have been proposed. However, even if these techniques are used, depending on the production conditions such as adding a heating step during production, or the combination with other raw materials such as containing ethylhexyl methoxycinnamate in the formulation, the metal oxide having a small average particle diameter may be used. Dispersion stability may be insufficient.

However, in the technique of Patent Document 1, there is a problem that by applying a surface treatment to a solid compound, it lacks smoothness when applied to the skin, resulting in poor spread. In the technique of Patent Document 2, it is necessary to contain a large amount of silicone oil in the oil phase, and it is difficult to contain a poorly compatible oil agent, for example, a solid ultraviolet absorber, etc., and there is a limitation in the prescription width. There was a problem. Further, the technique of Patent Document 3 has a problem that the dispersibility of the powder becomes insufficient when ethylhexyl methoxycinnamate is contained.
Therefore, it has been demanded to develop a composition having excellent dispersion stability, good spread of spread, and lack of skin whiteness after application.
In general, metal oxides have strong cohesive properties. In particular, in a composition containing a metal oxide in ethylhexyl methoxycinnamate, the metal oxide may easily aggregate. On the other hand, in order to suppress further agglomeration, it has been conventionally performed to hydrophobize the metal oxide surface in advance. However, the composition such as cosmetics may not have sufficient effect of suppressing aggregation due to other components contained therein.

  Under such circumstances, the inventor has intensively studied the third component for further improving the stability. At that time, it was found that combining some kind of oil was unexpectedly effective in dispersion stability. That is, an attempt was made to change the dispersion state of ethylhexyl methoxycinnamate and metal oxide by combining with an oil agent having a polarity different from that of ethylhexyl methoxycinnamate. When examining such an oil agent, for example, as a result of examining various characteristics such as a component having a branched structure and a component having an unsaturated bond, a component having a hydroxyl group in a part of the molecular structure or a component having a cyclic structure in the molecule is found. As a result of finding that there is a tendency to be excellent in dispersibility and further studying it, it was found that p-menthane-3,8-diol is particularly excellent.

That is, the present invention includes the following components (a) to (c):
(A) A metal oxide having an average particle diameter of 1 to 100 nm and having been hydrophobized (b) p-menthane-3,8-diol (c) ethylhexyl methoxycinnamate is provided. .

  The composition (a) / (b) of the said components (a) and (b) provides the composition whose range is 0.5-5.

  A composition in which the metal oxide of the component (a) is zinc oxide or titanium oxide is provided.

  The component (a) provides a composition that is hydrophobized with triethoxycaprylylsilane.

  The present invention provides a composition that is a cosmetic.

  Compositions that are oil-in-water are provided.

  A composition that is a sunscreen cosmetic is provided.

  The composition of the present invention is excellent in the dispersion stability of the metal oxide subjected to the hydrophobization treatment with an average particle diameter of 1 to 100 nm, the good spread and the skin whiteness after coating.

For example, a hydrophobic treatment agent and powder particles to be treated are added to a solvent, stirred with a ball mill or the like, then dried as necessary, washed with water and filtered repeatedly to remove impurities, and then dried. The desired hydrophobized powder can be obtained by pulverization. Further, several types of compounds that are surface treatment agents can be simultaneously surface treated, and after surface treatment with any one compound in advance, other compounds can be surface treated. The amount of treatment varies depending on the type of surface treatment agent, the combination thereof, and the type of powder to be treated, and is not particularly limited. % (Hereinafter simply referred to as “%”) is preferable.
